Johnson was drafted by the Houston Astros in the fourth round of the 06 MLB draft. Johnson was called up to the majors for the first time on September 7, 2009. In the 2010 Season, he batted .308 with 105 Hits, 22 Doubles, 11 HR's, and 52 RBI's in just 341 at bats. He looks like the odds on favorite to make the start at 3rd base this season but Brett Wallace is right on his heels and if Johnson can pick up production on the offensive side of the ball he can be a strong part of the infield and all around good piece to the Astros puzzle. He has all the tools to be a serviceable player but does need some more time to develop and with the right coaching he can be that player sooner than later.
